Here is the situation: I'm using two separate browsers (IE8 & FF3.6) to test the application at the same time.
I have a form that takes contact information (name, address, email, etc.) I access the form (http://localhost:9084/demosite/contactus.action) from IE8 and type the first name and hit the submit button. The validation fails and the page is displayed with the first Name still filled in and the correct error messages displayed (Last Name Required, etc.). BTW, That's is what I expected. But here is the odd problem that I'm seeing: I then open up FF3.6 and enter the URL http://localhost:9084/demosite/contactus.action I see the page displayed with the same info (First Name filled in and error messages displayed) that I have in the IE8 browser. I'm using struts2-core-2.1.8.1 and running it under Websphere 7.0.0.9. I'm sure I have a setup issue, but really don't know what it could be, other than that the application is working fine no error messages in the logs.
